摘要： A toner supply device includes a toner container, a transport-path forming member, an opening, a shutter member, and a first seal member. The opening is provided at a side wall of the transport-path forming member. The shutter member is movable between a closed position to close the transport path by being inserted in the opening and an open position. The first seal member fills a gap between an inner wall of the opening and the shutter member in a toner transport direction in which the toner is transported through the transport path. When the shutter member is inserted in the opening, the shutter member is elastically deformable in a deformation direction perpendicular to both the toner transport direction and a moving direction of the shutter member, and when the shutter member is not inserted in the opening, the shutter member is wider than the opening in the deformation direction.

摘要： To provide a relatively small developing device, process cartridge and image forming apparatus that prevent developer, accommodated in a second developer conveying portion for recovering the developer after a developing step, from being pumped up to a developer carrier, and that do not apply a large stress to the developer. A plurality of developer carriers are arranged side-by-side in a direction of gravitational force so as to face an image carrier. The developing device comprises a first developer conveying portion that supplies the developer to a first developer carrier, a second developer conveying portion that recovers the developer separated from the second developer carrier, and a third developer conveying portion that conveys the developer obliquely upward and conveys, to an upstream side in a conveyance direction of the first developer conveying portion, the developer reaching the downstream side in the conveyance direction of the first developer conveying portion and the developer reaching a downstream side in a conveyance direction of the second developer conveying portion.

摘要： A developing device includes a developer bearer and a stirring conveyor. The stirring conveyor includes a first conveying chamber including a conveying member and a second conveying chamber to receive the developer from an end of the first conveying chamber. The conveying member includes a forward winding blade, a reverse winding blade, and a shaft portion on which the forward winding blade and the reverse winding blade are mounted with a space therebetween. A circumferential phase of the conveying member at a start position of the reverse winding blade is different from a circumferential phase of the conveying member at an end position of the forward winding blade. The conveying member is disposed in the first conveying chamber so that the space is opposite a portion at which the second conveying chamber receives the developer from the end of the first conveying chamber.

摘要： The present invention provides a communication connector arranged on an image-forming apparatus body to provide communications with an information storage device including a guide portion and installed on a detachable device. The connector includes a body terminal which, when the detachable device is attached to the apparatus body, contacts a contact terminal of the information storage device, and a body projection extending in a moving direction of the detachable device and having a slope at its distal end. The body terminal is arranged on the body projection and configured not to project further than the slope, to be exposed to outside from a portion other than the slope, and to contact the contact terminal inside the guide portion when the body projection is inserted thereinto. An inclination angle θ of an end portion of the slope is not smaller than an inclination angle θ1 of the slope.
